1st actual powered flight of a heavier than air craft - Wright Brothers - OHIO

DaVinci designed and built a glider that injured the pilot and he abandonded ever trying it again. He also did some drawings of what some say might be the beginnings of a helicopter, but I don't think that would classify as being the inventor.

At least that is what I remember reading. I may have to do some research on those to verify it.
